Research progress on the expression and distribution of severe acute respiratory syndrome coronavirus 2 receptor angiotensin-converting enzyme 2 in ocular tissues / 国际眼科杂志(Guoji Yanke Zazhi)

Since 2019,severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)posed a great threat to human health and social economy, which has brought out hundreds of millions infection and caused millions of deaths worldwide. With the increasing research on SARS-CoV-2, angiotensin-converting enzyme 2(ACE2)has been regarded as a significant functional receptor for SARS-CoV-2 invasion. ACE2 is distributed in many tissues of human body, not only expressed in lung, cardiovascular, kidney tissues, but also in conjunctiva, cornea, uvea, retina and optic nerve tissue. More and more cases of SARS-CoV-2 infection through ocular tissues have been found; however, whether ocular ACE2 plays a role in SARS-CoV-2 infection is not completely clear. Therefore, study on expression and distribution of ACE2 in the ocular tissues can not only provide an in-depth understanding of the mechanism of SARS-CoV-2 infection, but also supply a comprehensive acquaintance with the mechanism of ACE2 action in the ocular tissues. In this paper, we review recent research progress about the expression and distribution of ACE2 in ocular tissues and hope to better understand the mechanism of ACE2 in the pathophysiological processes of ocular tissues.

Glaucoma uveítico como síndrome paraneoplásico asociado a cáncer de mama / Uveitic glaucoma as paraneoplastic syndrome with breast cancer

Introducción: Los síndromes paraneoplásicos son manifestaciones sistémicas asociadas a ciertos cánceres no relacionados con la invasión local del tumor o metástasis. Su importancia clínica radica en que pueden constituir el primer signo de enfermedad; así pues, el glaucoma uveítico constituye en este caso la primera manifestación del cáncer de mama. Método: Relato del caso, revisión de literatura, experiencia clínica y de investigación personal. Resultados: Se debe tener especial atención en la evolución favorable o no del tratamiento, si este no logra la resolución de las manifestaciones oftalmológicas, se debe investigar y valorar los factores de riesgo de neoplasia del paciente, para ello, se practicó mamografía y biopsia mamaria, y se corroboró el diagnóstico de cáncer de mama invasivo con una gammagrafía. Conclusión: Este caso ilustra la importancia de incluir manifestaciones oculares como uveítis y glaucoma como síndrome paraneoplásico asociado a cáncer de mama

Introduction: Paraneoplastic syndromes are systemic manifestations associated with certain cancers not related to the local invasion of the tumor or metastasis. The clinical importance lies in the fact that they can constitute the first sign of disease; in this case, Uveitic Glaucoma constitutes the first manifestation of breast cancer. Methods: A case report, literature review, clinical and personal research experience. Results: Special attention should be paid to the favorable or negative evolution of the treatment, if it does not achieve the resolution of the ophthalmological manifestations, investigate and assess the risk factors for neoplasia of the patient, for this, mammography and breast biopsy were performed and final diagnosis of Invasive Breast Cancer was corroborated with scintigraphy. Conclusion: This case illustrates the importance of including ocular manifestations such as uveitis and glaucoma as a paraneoplastic syndrome associated with breast cancer.

Melanocytoma of the optic disk: A review

Melanocytoma is a deeply pigmented variant of melanocytic nevus that classically occurs in the optic disk, sometimes with contiguous involvement of the adjacent retina or choroid. Historically, this tumor was often confused with malignant melanoma both clinically and histopathologically. Today, however, it is generally recognized by its typical clinical features that differ from most melanomas and erroneous enucleation is rarely done. Histopathologically, melanocytoma is composed of intensely pigmented round to oval nevus cells with benign features. Although traditionally believed to be a relatively stationary lesion, it is now known to exhibit minor enlargement in 10--15% of cases and can cause minor visual loss by a variety of mechanisms. In rare instance, it can induce severe visual loss due to spontaneous necrosis of the lesion or compressive optic neuropathy. More importantly, it can exhibit malignant transformation into melanoma in 1--2% of cases. Ophthalmologists should be familiar with melanocytoma of the optic disk and affected patients should be followed periodically.

Multifocal choroidal melanoma in oculodermal melanocytosis in an Asian Indian

A 51-year-old Asian Indian male with right oculodermal melanocytosis presented with a blurred visual acuity of 20/40. Upon fundus examination, he was discovered to have two independent pigmented choroidal melanomas in the temporal juxtapapillary region and inferiorly, in the region of trace clinical sectoral choroidal melanocytosis. The patient underwent enucleation, and on histopathology the two tumors were found to be in the area of choroidal melanocytosis, in continuity with each other. Multifocal choroidal melanoma is an exceedingly rare diagnosis. Ocular melanocytosis is a known predisposing factor for both unifocal and multifocal melanomas. Lifelong monitoring for uveal melanomas must be done in all patients with ocular melanocytosis.

Sympathetic ophthalmia with incidental finding of chicken pox supported by histopathology and immunohistochemistry

Sympathetic ophthalmia (SO) is a rare bilateral diffuse granulomatous panuveitis that occurs in few days to several years after penetrating injury. This intraocular inflammation can occur in any age group without a sex predilection. Pathology and immunohistochemistry-supported evidence is important to know the disease in a better way. We present a case of a 24-year-old female with clinical diagnosis of SO with an atypical past history of chicken pox in that eye and residual corneal opacity.

Corneoconjunctival manifestations of lymphoma in three dogs

An 8-year-old Shih Tzu, a 5-year-old Maltese, and a 10-year-old Maltese presented with conjunctival hyperemia and peripheral corneal edema. Severe conjunctival thickening with varying degrees of corneal extension was observed. Cytological examination showed many large lymphocytes with malignant changes in the conjunctiva which was consistent with findings in fine-needle aspiration samples taken from regional lymph nodes. They were diagnosed as having Stage V multicentric lymphoma. When conjunctival thickening is observed in canine patients with multicentric lymphoma, conjunctival metastasis with infiltration of neoplastic lymphoid cells should be included in the differential diagnosis.

Unilateral floppy eyelid syndrome with ipsilateral intolerance to brimonidine / Síndrome da palpebral flácida unilateral com intolerância a brimonidina ipsilateral

Abstract The authors report a case of unilateral floppy eyelid syndrome with ipsilateral intolerance to brimonidine in a 65-year-old man. The singularity of this case is the combination of two rare illnesses of great phlogistic potentiality in the same eye. The purpose of this article is to report a case of unilateral floppy eyelid syndrome with ipsilateral intolerance to brimonidine, emphasizing a possible relation between them. The result was a unilateral keratopathy that emulated an intraepithelial neoplasia. The key to solving the problem was an unexplained anterior uveitis that raised the suspicion of drug toxicity.The upper eyelid eversion of the affected eye during sleep seemed to be the common denominator of both ailments. The bizarre aspect of the epitheliopathy most likely resulted from the combination of trauma, insufficient lubrication, and drug intolerance.

Resumo Os autores relatam um caso de síndrome da pálpebra flácida unilateral com intolerância ipsilateral à brimonidina em um homem de 65 anos de idade. A singularidade deste caso é a combinação de duas doenças raras de grande potencialidade inflamatória no mesmo olho. O objetivo deste artigo é relatar um caso de síndrome da pálpebra flácida com intolerância ipsilateral à brimonidina, enfatizando uma possível relação entre eles. O resultado foi uma ceratopatia unilateral que simulou uma neoplasia intra-epitelial. A chave para resolver o problema foi uma uveíte anterior inexplicável que levantou a suspeita de toxicidade medicamentosa. A eversão da pálpebra superior do olho afetado durante o sono parece ser o denominador comum de ambas as doenças. O aspecto bizarro da epiteliopatia provavelmente resultou da combinação de trauma, lubrificação insuficiente e intolerância ao medicamento.

Choroidal metastases: Origin, features, and therapy.

The choroid is the most common ocular site for metastatic disease, owing to abundant vascular supply. The primary cancers that most commonly lead to choroidal metastases include breast cancer (40-47%) and lung cancer (21-29%). Bilateral, multifocal metastases are most often secondary to breast cancer, whereas unilateral, unifocal metastasis are more commonly found with lung cancer. The treatment of choroidal metastasis depends on the systemic status of the patient and number, location, and laterality of the choroidal tumors. Treatment options include observation in patients with poor systemic status or those with resolved or asymptomatic disease; systemic chemotherapy, immunotherapy, hormone therapy, or whole eye radiotherapy if the metastases are active, multifocal and bilateral; plaque radiotherapy, transpupillary radiotherapy, or photodynamic therapy for active, solitary metastasis; and enucleation for those with blind painful eye. A database search was performed on PubMed, using the terms “choroidal metastasis,” or “choroidal metastases,” in combination with terms such as “treatment,” “features,” or “diagnosis.” Relevant articles were extracted and reviewed.

Phenotypes,distribution, and morphological features of antigen-presenting cells in the normal murine iris / 中华实验眼科杂志

Background The conventional study of antigen-presenting cells(APCs)in eye relies on in vitro histoimmunochemistry,but its outcome is influenced by many factors.The anterior chamber injection of fluoresceinmarked antibody was used as a new approach before,however,it is liable to lead to injury of cornea.The intravitreal injection of fluorescein-labeled antibody may be important for the in vivo study of the phenotype features of APCs in iris,which is significant for evaluating the function of APCs in immune homeostasis.Objective This study was to investigate the phenotype characters,distribution and morphology of different types of APCs in the normal murine iris.Methods Fifty-one SPF female BALB/c mice(from 6-to 8-week old)were randomized into 17 groups according to the injection of different antibodies.Alexa Fluor 594 or Alexa Fluor 488-tagged ovalbumin (OVA),CD11 c,major histocompatibility complex Ⅱ (MHC-Ⅱ),F4/80,B7-1 and B7-2 monoclonal antibodies or mixtures of two antibodies (2.0 μl)were intravitreally injected at 0.5 mm far from corneal limbus with microneedle under the biomicroscope.The iris tissues were isolated 24 hours after injection.The phenotype characters,precise distribution and morphology of different types of APCs were identified by epifluorescence microscope and laser confocal microscope.In vitro staining was also performed to validate the in vivo staining results.Results After in vivo staining via intravitreal injection,the cell positive for OVA as well as MHC-Ⅱ,F4/80,CD11 c,B7-1 and B7-2 were exhibited with the regular networkline appearance throughout the normal murine iris.Positive cells tagged with Alexa Fluor 594 or Alexa Fluor 488 presented the red or green fluorescence.Double-fluorescein staining showed that about 90％ of F4/80+ cells were OVA+,and MHC-Ⅱ was expressed in about 60％ of F4/80+ cells and CD11c+cells,and about 35％ of F4/80+ cells and CD1 1 c+ cells expressed B7-1 and B7-2 simultaneously,and over 70％ of OVA+ cells were positive to MHC-Ⅱ.These labeled cells were identified as two populations based on their shape.One type was dendritiform cell (DC) with a small cell body and many long dendrites,including OVA+,CD1 1 c+,F4/80+ cells and MHC-Ⅱ + cells ; and the other types were polymorphic population being round,pleomorphic or irregular shape with a large cell body and a few short dendrities,including B7-1 + and B7-2+ cells.Conclusions In vivo intravitreal injection of labeled antibodies can be adapted to visualize the labeled cells in the murine iris.APCs with distinct morphologies,phenotypes and distribution may contribute to the immunologically privileged feature and inflammation of the eye.

The possible causes include infections or alterations in the immune system and can be primarily visual or associated with a systemic disease. It´s incidence is proportional in men and women, and it depends on the disease it's associated to. Medical and Dental diagnosis is generaly made by physical and radiographic examination, along with laboratory tests. The treatment will depend on the symptoms of the patient.

Uveitis manifestaciones secundaria de infección en cavidad bucal: reporte de caso clínico / Uveitis: as a symthom of oral infection: report a case

La uveítis es una patología ocular que se define como la inflamación del tracto uveal del ojo, que pudiera estar asociada a la inflamación de otras estructuras oculares o adyacentes a la cavidad orbitaria, por la proximidad que hay entre los tejidos. En el campo odontológico la uveitis se manifiesta de manera secundaria ante infecciones focales, las cuales se caracterizan por presentar un foco séptico primario, en donde la infección se propaga a otras estructuras del macizo facial. Entre las lesiones que generan un foco infeccioso primario en cavidad bucal, se describen: quiste periapical, granuloma periapical, afecciones pulpares, pericoronaritis y enfermedad periodontal, siendo esta última motivo del caso clínico que se presenta a continuación

Uveitis is an eye condition that is defined as inflammation of the uveal tractor and may be associated with inflammation of other ocular structures or adjacent to the orbital cavity, and the proximity between the tissues. In the dental field uveitis manifests itself secondary to focal infections, which are characterized by a primary septic focus, where the infection spreads to other craniofacial structures. Among lesions that produce a primary infection in oral cavity, are described: periapical cyst, periapical granuloma, pulpal disease, and periodontal disease pericoronaritis, the latter being the occasion of the clinical case is presented below

Melanoma de iris con invasión al ángulo camerular / Iris melanoma invading the camerular angle

Los melanomas uveales son los tumores intraoculares primarios más frecuentes, con una incidencia de 8/1 000 000 al año en la raza blanca. Específicamente el melanoma de iris representa entre 5 y 7 % de los melanomas malignos de la úvea. Estos tumores pueden ser amelánicos o pigmentados y por lo general muy vascularizados. Se presenta un paciente de 18 años con antecedentes de salud, que fue atendido en el cuerpo de guardia de oftalmología refiriendo dolor ocular y disminución brusca de la visión del ojo derecho. En el examen físico se constató hipertensión ocular marcada, hifema de 2 mm, y edema corneal. Este cuadro cedió con tratamiento y permitió observar una tumoración del iris que invadía el ángulo iridocorneal, muy vascularizada. Por esto se realizaron exámenes en busca de tumores a otros niveles, y finalmente una biopsia por aspiración con aguja fina. Se concluye el caso con el diagnóstico de un melanoma de iris con invasión a cuerpo ciliar. El paciente se remite para tratamiento quirúrgico al Instituto Nacional de Oncología y Radiobiología.

Uveal melanomas are the most frequent primary uveal tumors, having an incidence of 8/1 000 000 a year in Caucasian people. Specifically, iris Melanoma represents 5 to 7 % of the uveal malignant melanomas and they may be amelanic or pigmented, generally very vascularized. An eighteen years old male patient with a history of health problems was presented, who had been seen at the Ophthalmological Emergency Service because of eye pain and sudden visual reduction in his right eye. In the physical exam, a marked ocular hypertension was confirmed as well as a 2 mm hyphema and corneal edema. These conditions were overcome with treatment and afterwards, there was observed iris tumoration invading the iridocorneal angle. Some complementary studies were carried out to search further tumors at other levels and finally a fine needle aspiration biopsy was performed. The diagnosis was amelanic Iris Melanoma invading the ciliary body. The patient was referred for surgical treatment at the National Institute of Oncology and Radiology.

En la casuística predominaron los afectados por uveítis del segmento anterior, que presentaron mayor número de síntomas en general y por paciente. Se encontró una relación significativa entre los resultados de los exámenes inmunológicos y la presencia de la oftalmopatía, con predominio de la visión borrosa o disminución de la agudeza visual.

A descriptive, cross-sectional and prospective study was carried out to determine the epidemiological characteristics of 55 patients with inflammatory diseases of the uvea and who were assisted at the Ophthalmology Service of Saturnino Lora Teaching Provincial Hospital in Santiago de Cuba, from January to December, 2006. Those affected by uveitis of the previous segment that presented a higher number of symptoms in general and by patient prevailed in the case material. A significant relationship between the results of the immunologic tests and the presence of ophthalmopathy was found, with prevalence of blurred vision or decrease of visual acuity.

A necrotic ciliochoroidal malignant melanoma in a young Thai female

Background: Uveal malignant melanoma is not common among Asians and is rare in young people. Extensive necrosis of a tumor without prior treatment has scarcely been reported. Objective: To study the histopathology findings of a large uveal mass in a young female. Method: Review of clinical history, physical examination, ultrasonography, radiography, and histopathology were performed. Results: A 14-year-old Thai female with a past history of trauma presented with visual loss in her left eye. Total lens opacity was found. During the lens aspiration procedure, a dark ciliochoroidal mass was detected. A large uveal melanoma was suspected. The enucleated eye consisted of an extensively necrotic ciliochoroidal malignant melanoma with only tiny foci of the epithelioid cells at the tumor base. There was no extrascleral extension. A systemic work-up did not show extraocular involvement. Conclusion: We report a rare case of a large, necrotic type, uveal melanoma in a teenage Thai female.

Clinical observation of injection of triamcinolone acetonide into the anterior chamber for anterior uveitis after cataract combined with anti-glaucoma surgery / 眼科研究

Background Anterior uveitis is a common complication following the combination procedure of cataract extraction and anti-glaucoma surgery.More and more researches demonstrated the anti-inflammatory effectiveness of intraocular injection of triamcinolone acetonide (TA).Objective This study aims to observe the anti-inflammatory effectiveness of anterior chamber injection of TA for anterior uveitis following cataract extraction combined with anti-glaucoma surgery.Methods This is a case-control study.The clinical data from 42 eyes of 42 cases underwent the combination surgery of catarat extraction and anti-glaucoma was retrospectively reviewed and analyzed.The operation was performed by the same ophthalmologist on all patients.Twenty-one eyes (21 case) receiving conjunctiva injection of dexamethasone (Dex) in intraoperation served as the control group and the matched cases who received anterior chamber injections of TA in intraoperation were regarded as the TA group.The anterior uveitis was graded according to the Standard of Yang~([3]),and the intraocular pressure(IOP) was measured 1,3,and 7 days after surgery.Written informed consent was obtained from each patient before the initiation of any study protocol.Results The numbers of eyes with severe anterior uvetitis were significantly decreased 1,3,7 days after operation in the TA group in comparison with the Dex group (χ~2=10.857,P=0.028;χ~2=8.467,P=0.037;χ~2=11.286,P=0.004 ).No significant differences were found in IOP values between the TA group and the Dex group 1,3,7 days after operation (19.12±3.27 versus 19.49±3.23mmHg,t=0.469,P=0.644;17.91±1.95 versus 17.06±2.90mmHg,t=1.257,P=0.223;13.67±1.68 versus 13.05±1.66mmHg,t=1.201,P=0.237,respectively).Mild edema of corneal endothelium was seen in the early stage after operation and dissipated 4 days later in both groups,no significant differences were found between the TA group and the Dex group (P＞0.05).Conclusion TA can effectively inhibit the inflammatory reaction of anterior uvea after cataract combination with anti-glaucoma surgery.No severe adverse effect is found after anterior chamber injection of TA.

Alterações do segmento posterior na microftalmia: relato de casos / Posterior segment changes in microphthalmic eyes: case report

Microftalmia é a alteração de desenvolvimento caracterizada pela redução do tamanho do bulbo ocular. Pode estar associada a manifestações estruturais do segmento anterior e posterior. As alterações mais comuns do segmento anterior são as opacidades corneanas, o estreitamento e fechamento do ângulo da câmara anterior e a catarata, e as mais frequentes no segmento posterior são a efusão uveal, as dobras de retina, a alteração da vascularização capilar macular, a ausência de depressão foveal e a retinosquise periférica. Este estudo descreve o caso de três pacientes com microftalmo e manifestações no segmento posterior documentadas com tomografia de coerência óptica. O primeiro caso apresentou a síndrome de efusão uveal, com descolamento de coróide e de retina, tratada com cirurgia de esclerectomia parcial nos quatro quadrantes. No segundo caso, havia a dobra retiniana neurossensorial na fóvea e feixe papilomacular em ambos os olhos sem o envolvimento de epitélio pigmentado retiniano e coriocapilar. No terceiro paciente, o microftalmo estava acompanhado de ausência da depressão foveal, cujo principal diagnóstico diferencial é a hipoplasia foveal.

Microphthalmos is a developmental ocular disorder defined as a small eyeball. The condition can be associated with abnormalities of anterior and posterior segments. The most common anterior characteristics include corneal opacities, angle-closure and a shallow anterior chamber and cataract. The main findings of posterior segment are uveal effusion, retinal folds, abnormalities of macular capillar vascularization, absence of foveal depression and peripheral retinoschisis. Three patients with microphthalmos were assisted and their OCT features of posterior segment were analyzed. The first case had uveal effusion syndrome, choroidal and retinal detachment treated with parcial sclerectomy at the four quadrants. The other case presented with neurosensory retinal fold at fovea and papillomacular area in both eyes without involvement of retinal pigment epithelium layer and choriocapillaris. The third patient showed absence of foveal depression. The main diferencial diagnosis for this condition is foveal hypoplasia.
